highly significantP = 0.007
There was highly significant association between outcome of the patient (survival/non-survival) and severity of the CRP levels (Fisher's exact = 11.508, P = 0.007), d-Dimer levels (Pearson's Chi-square = 11.714, P = 0.008), serum ferritin levels (Pearson's Chi-square = 15.608, P = 0.001), and HRCT score (Fisher's exact = 18.694, P = 0.000).
